you can use the ip utility to create dummy network devices on top of
your
loopback device, but the better question is - why? Having multiple clients and
servers on a single system doesn't in any way require multiple loopback
interfaces. just have the servers and clients all listen on, and connect to
127.0.0.1, and assign each server a separate port number.
that does not help you much in case as example a multi-postfix-installation
when the software is not interested in using a different port and you
want simulate real world by different IP's, binding services to specific
ones and work with *hostnames* via /etc/hosts
